Punica granatum plant named &#39;orange blossom special&#39;

ABSTRACT

A new and distinct cultivar of  Punica granatum  plant named ‘Orange Blossom Special’, characterized by its compact, mounding growth habit, small, lustrous, medium green foliage that turns bright yellow in fall, reddish-orange flowers produced in abundance from spring to fall, greenish-tan to reddish-green fruits, and root/crown cold hardiness to USDA Hardiness Zone 7.

GENUS AND SPECIES OF PLANT CLAIMED

Punica granatum L.

VARIETY DENOMINATION

‘Orange Blossom Special’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Punica granatum, a member of the Punicaceae family, hereinafter referred to by its cultivar name ‘Orange Blossom Special’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant.

The cultivar originated from an open-pollination of Punica granatum ‘Nana’ (unpatented) in Watkinsville, Ga., and was selected from the progeny of this pollination by continued evaluation for growth habit and flowering and fruiting characteristics.

‘Orange Blossom Special’ has been asexually reproduced by softwood cuttings since 2007 in Watkinsville, Ga. The characteristics of ‘Orange Blossom Special’ have been stable and reproduced true-to-type in successive vegetative generations.

SUMMARY OF THE INVENTION

‘Orange Blossom Special’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been observed and represent the characteristics of ‘Orange Blossom Special’. In combination these characteristics distinguish ‘Orange Blossom Special’ from all other varieties in commerce known to the inventor. 1) Compact, mounding growth habit. 2) Small, lustrous, medium green foliage that turns bright yellow in fall. 3) Reddish-orange flowers produced in abundance from spring to fall. 4) Greenish-tan to reddish-green fruits. 5) Root/crown cold hardiness to USDA Hardiness Zone 7.

‘Orange Blossom Special’ is distinguished from its female parent ‘Nana’ by its vigor, growth habit, flower color, and quantity of flowers and fruit produced. ‘Orange Blossom Special’ has a more vigorous, mounding growth habit, whereas ‘Nana’ has a less vigorous rounded growth habit. ‘Orange Blossom Special’ has reddish-orange flowers, whereas ‘Nana’ has orange flowers. ‘Orange Blossom Special’ flowers and fruits more prolifically than ‘Nana’. There are no other cultivars of Punica granatum with this combination of characteristics known to the inventor.

Plants of ‘Orange Blossom Special’ can be compared to plants of the cultivar ‘PIIPG-I’ (U.S. Plant Pat. No. 21,031), a sibling of ‘Orange Blossom Special’, which originated from the same open-pollination of Punica granatum ‘Nana’. However, in side-by-side comparisons conducted in Watkinsville, Ga., plants of ‘Orange Blossom Special’ differed from plants of ‘PIIPG-I’ in the following characteristics: 1. Plants of ‘Orange Blossom Special’ had fruit that was greenish-tan to reddish-green in color, whereas plants of ‘PIIPG-I’ had fruit that was maroon-purple in color; 2. Plants of ‘Orange Blossom Special’ had a compact, mounding growth habit, whereas plants of ‘PIIPG-I’ had an overall larger compact, upright spreading growth habit; 3. Plants of ‘Orange Blossom Special’ were less cold hardy than plants of ‘PIIPG-I’ in container and in-ground evaluations at Watkinsville, Ga.

DETAILED DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the description were grown in 11.8 L containers in full sun under outdoor conditions in a nursery in Watkinsville, Ga. Plants were approximately 2½ years old when the description was recorded.
